Tire pressure

Tire Pressure Monitoring System (TPMS)

WARNING

Radio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use.

This vehicle is equipped with the Tire Pressure Monitoring System (TPMS). It monitors tire pressure of all tires. When the low tire pressure warning light is lit, and the "Tire Pressure Low - Add Air" warning message is displayed in the vehicle information display, one or more of your tires is significantly under-inflated.

The TPMS will activate only when the vehicle is driven at speeds above 16 MPH (25 km/h). Also, this system may not detect a sudden drop in tire pressure (for example a flat tire while driving).

For more details, see "Low tire pressure warning light", "Tire Pressure Monitoring System (TPMS)" and "Tire Pressure Monitoring System (TPMS)".

Tire inflation pressure

Check the pressure of the tires often and always prior to long distance trips. The recommended tire pressure specifications are shown on the Tire and Loading Information label under the "Cold Tire Pressure" heading. The Tire and Loading Information label is affixed to the driver side center pillar. Tire pressures should be checked regularly because:

• Most tires naturally lose air over time.
• Tires can lose air suddenly when driven over potholes or other objects or if the vehicle strikes a curb while parking.

The tire pressures should be checked when the tires are cold.

The tires are considered COLD after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds.

TPMS with Easy Fill Tire Alert provides visual and audible signals outside the vehicle for inflating the tires to the recommended COLD tire pressure. Incorrect tire pressure, including under inflation, may adversely affect tire life and vehicle handling.

WARNING

• Improperly inflated tires can fail suddenly and cause an accident.
• The Gross Vehicle Weight Rating (GVWR) is located on the F.M.V.S.S./C.M.V.S.S. certification label. The vehicle weight capacity is indicated on the Tire and Loading Information label.

  Do not load your vehicle beyond this capacity. Overloading your vehicle may result in reduced tire life, unsafe operating conditions due to premature tire failure, or unfavorable handling characteristics and could also lead to a serious accident.

  Loading beyond the specified capacity may also result in failure of other vehicle components.

• Before taking a long trip, or whenever you heavily load your vehicle, use a tire pressure gauge to ensure that the tire pressures are at the specified level.
• For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.

Tire and Loading Information label

1. Seating capacity: The maximum number of occupants that can be seated in the vehicle.
2. Vehicle load limit: See "Vehicle loading information".
3. Original size: The size of the tires originally installed on the vehicle at the factory.
4. Cold tire pressure: Inflate the tires to this pressure when the tires are cold. Tires are considered COLD after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds. The recommended cold tire inflation is set by the manufacturer to provide the best balance of tire wear, vehicle handling, driveability, tire noise, etc., up to the vehicle's GVWR.
5. Tire size - see "Basic information".
6. Spare tire size or compact spare tire size (if so equipped)

Checking the tire pressure

1. Remove the valve stem cap from the tire.

2. Press the pressure gauge squarely onto the valve stem. Do not press too hard or force the valve stem sideways, or air will escape. If the hissing sound of air escaping from the tire is heard while checking the pressure, reposition the gauge to eliminate this leakage.

3. Remove the gauge.

4. Read the tire pressure on the gauge stem and compare it to the specification shown on the Tire and Loading Information label.

5. Add air to the tire as needed. If too much air is added, press the core of the valve stem briefly with the tip of the gauge stem to release pressure. Recheck the pressure and add or release air as needed.

6. Install the valve stem cap.

7. Check the pressure of all other tires.

Tire labeling

Basic information

Federal law requires tire manufacturers to place standardized information on the sidewall of all tires.

This information identifies and describes the fundamental characteristics of the tire and also provides the tire identification number (TIN) for safety standard certification.

The TIN can be used to identify the tire in case of a recall.

Example

1. Tire size (example: P215/60R16 94H)

1. P: The "P" indicates the tire is designed for passenger vehicles.

(Not all tires have this information.)

2. Three-digit number (215): This number gives the width in millimeters of the tire from sidewall edge to sidewall edge.

3. Two-digit number (60): This number, known as the aspect ratio, gives the tire's ratio of height to width.

4. R: The "R" stands for radial.

5. Two-digit number (16): This number is the wheel or rim diameter in inches.

6. Two- or three-digit number (94): This number is the tire's load index. It is a measurement of how much weight each tire can support. You may not find this information on all tires because it is not required by law.

7. H: Tire speed rating. You should not drive the vehicle faster than the tire speed rating.

Example (Type A) (if so equipped)

2. TIN (Tire Identification Number) for a new tire (example: DOT XX XX XXX XXXX)

1. DOT: Abbreviation for the "Department Of Transportation".

The symbol can be placed above, below or to the left or right of the Tire Identification Number.

2. Two-digit code: Manufacturer's identification mark

3. Two-digit code: Tire size

4. Three-digit code: Tire type code (Optional)

5. Four numbers represent the week and year the tire was built.

For example, the numbers 3103 means the 31st week of 2003. If these numbers are missing, then look on the other sidewall of the tire.

Example (Type B) (if so equipped)

2. TIN (Tire Identification Number) for a new tire (example: DOT XXX XXXXXX XXXX)

1. DOT: Abbreviation for the "Department of Transportation".

The symbol can be placed above, below or to the left or right of the Tire Identification Number.

2. Three-digit code: Manufacturer's identification mark 3. Six-digit code: Descriptive code used to identify significant characteristics of the tire.

4. Four numbers represent the week and year the tire was built.

For example, the numbers 3103 means the 31st week of 2003.

3. Tire ply composition and material
   The number of layers or plies of rubber-coated fabric in the tire.

   Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others.

4. Maximum permissible inflation pressure
   This number is the greatest amount of air pressure that should be put in the tire. Do not exceed the maximum permissible inflation pressure.
5. Maximum load rating
   This number indicates the maximum load in kilograms and pounds that can be carried by the tire.

   When replacing the tires on the vehicle, always use a tire that has the same load rating as the factory installed tire.

6. Term of "tubeless" or "tube type"
   Indicates whether the tire requires an inner tube ("tube type") or not ("tubeless").
7. The word "radial"
   The word "radial" is shown, if the tire has radial structure.
8. Manufacturer or brand name
   Manufacturer or brand name is shown.

Other tire-related terminology

In addition to the many terms that are defined throughout this section, Intended Outboard Sidewall is (1) the sidewall that contains a whitewall, bears white lettering or bears manufacturer, brand and/or model name molding that is higher or deeper than the same molding on the other sidewall of the tire, or (2) the outward facing sidewall of an asymmetrical tire that has a particular side that must always face outward when mounted on a vehicle.

Types of tires

Basic information

WARNING

• When changing or replacing tires, be sure all four tires are of the same type (Example: Summer, All Season or Snow) and construction.

  A NISSAN certified ARIYA dealer may be able to help you with information about tire type, size, speed rating and availability.

• Replacement tires may have a lower speed rating than the factory equipped tires, and may not match the potential maximum vehicle speed. Never exceed the maximum speed rating of the tire.
• Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS.
• For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.
• Always use tires of the same type, size, brand, construction and tread pattern on all four wheels.

  Failure to do so may result in a circumference difference between tires on the front and rear axles which can cause the Vehicle Dynamic Control (VDC) system to malfunction resulting in personal injury or death, excessive tire wear and may damage the transmission and differential gears.

All season tires

NISSAN specifies all season tires on some models to provide good performance all year, including snowy and icy road conditions.

All Season tires are identified by ALL SEASON and/or M&S (Mud and Snow) on the tire sidewall. Snow tires have better snow traction than All Season tires and may be more appropriate in some areas.

Summer tires

NISSAN specifies summer tires on some models to provide superior performance on dry roads. Summer tire performance is substantially reduced in snow and ice.

Summer tires do not have the tire traction rating M&S on the tire sidewall.

If you plan to operate your vehicle in snowy or icy conditions, NISSAN recommends the use of SNOW tires or ALL SEASON tires on all four wheels.

Snow tires

If snow tires are needed, it is necessary to select tires equivalent in size and load rating to the original equipment tires. If you do not, it can adversely affect the safety and handling of your vehicle.

Generally, snow tires will have lower speed ratings than factory equipped tires and may not match the potential maximum vehicle speed. Never exceed the maximum speed rating of the tire.

If you install snow tires, they must be the same size, brand, construction and tread pattern on all four wheels.

For additional traction on icy roads, studded tires may be used. However, U.S.

states and Canadian provinces prohibit their use. Check local, state and provincial laws before installing studded tires. Skid and traction capabilities of studded snow tires, on wet or dry surfaces, may be poorer than that of non-studded snow tires.

Tire chains

CAUTION

• Tire chains/cables should not be installed on 255/45 R20 tires.

  Doing so will cause damage to the vehicle.

• If you plan to use tire chains/ cables, you should install 235/55 R19 tires on your vehicle.

Use of tire chains may be prohibited according to location. Check the local laws before installing tire chains. When installing tire chains, make sure they are the proper size for the tires on your vehicle and are installed according to the chain manufacturer's suggestions.

Use only SAE Class S chains. Class "S" chains are used on vehicles with restricted tire to vehicle clearance. Vehicles that can use Class "S" chains are designed to meet the SAE standard minimum clearances between the tire and the closest vehicle suspension or body component required to accommodate the use of a winter traction device (tire chains or cables). The minimum clearances are determined using the factory equipped tire size. Other types may damage your vehicle.

Use chain tensioners when recommended by the tire chain manufacturer to ensure a tight fit. Loose end links of the tire chain must be secured or removed to prevent the possibility of whipping action damage to the fenders or underbody. If possible, avoid fully loading your vehicle when using tire chains. In addition, drive at a reduced speed. Otherwise, your vehicle may be damaged and/or vehicle handling and performance may be adversely affected.

Tire chains must be installed only on the front wheels and not on the rear wheels.

Do not use tire chains on dry roads. Driving with tire chains in such conditions can cause damage to the various mechanisms of the vehicle due to some overstress.

Changing wheels and tires

Tire rotation

NISSAN recommends rotating the tires at the specified interval shown in the maintenance schedule. (For tire replacing procedures, see "Jacking up vehicle and replacing tires") As soon as possible, tighten the wheel nuts to the specified torque with a torque wrench.

Wheel nut tightening torque: 80 ft-lb (108 N·m)

The wheel nuts must be kept tightened to the specification at all times. It is recommended that wheel nuts be tightened to the specification at each tire rotation interval.

WARNING

• After rotating the tires, check and adjust the tire pressure.
• Retighten the wheel nuts when the vehicle has been driven for 600 miles (1,000 km) (also in cases of a flat tire, etc.).
• For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.
• After rotating the tires, do not use the Easy-Fill Tire Alert to adjust the tire pressure.

  Instead use a gauge to adjust the tires to the correct pressure in accordance with Tire and Loading Information label.

• To ensure proper operation of the Easy-Fill Tire Alert system after a tire rotation, reset and register the sensor to their new installed locations.

  It is recommended that you visit a NISSAN certified ARIYA dealer for this service.

Tire wear and damage

1. Wear indicator
2. Wear indicator location mark

WARNING

• Tires should be periodically inspected for wear, cracking, bulging or objects caught in the tread. If excessive wear, cracks, bulging or deep cuts are found, the tire(s) should be replaced.
• The original tires have built-in tread wear indicators.

  When wear indicators are visible, the tire(s) should be replaced.

• Tires degrade with age and use. Have tires over 6 years old checked by a qualified technician, because some tire damage may not be obvious. Replace the tires as necessary to prevent tire failure and possible personal injury.
• For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.

Replacing wheels and tires

When replacing a tire, use the same size, tread design, speed rating and load carrying capacity as originally equipped.

WARNING

• The use of tires other than those recommended or the mixed use of tires of different brands, construction (bias, bias-belted or radial), or tread patterns can adversely affect the ride, braking, handling, VDC system, ground clearance, body-to-tire clearance, tire chain clearance, speedometer calibration, headlight aim and bumper height. Some of these effects may lead to accidents and could result in serious personal injury.
• For Two-Wheel Drive (2WD) models, if your vehicle was originally equipped with 4 tires that were the same size and you are only replacing 2 of the 4 tires, install the new tires on the rear axle. Placing new tires on the front axle may cause loss of vehicle control in some driving conditions and cause an accident and personal injury.
• If the wheels are changed for any reason, always replace with wheels which have the same offset dimension. Wheels of a different off-set could cause premature tire wear, degrade vehicle handling characteristics and/or interference with the brake discs/drums. Such interference can lead to decreased braking efficiency and/or early brake pad/shoe wear. See "Wheels and tires" of this manual for wheel off-set dimensions.
• Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS.
• The TPMS sensor may be damaged if it is not handled correctly. Be careful when handling the TPMS sensor.
• When replacing the TPMS sensor, the ID registration may be required. It is recommended you visit a NISSAN certified ARIYA dealer for ID registration.
• Do not use a valve stem cap that is not specified by NISSAN. The valve stem cap may become stuck.
• Be sure that the valve stem caps are correctly fitted. Otherwise the valve may be clogged up with dirt and cause a malfunction or loss of pressure.
• Do not install a damaged or deformed wheel or tire even if it has been repaired. Such wheels or tires could have structural damage and could fail without warning.
• The use of retread tire is not recommended.
• For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.

All-Wheel Drive (AWD) models

CAUTION

Always use tires of the same size, brand, construction (bias, bias-belted or radial), and tread pattern on all four wheels. Failure to do so may reduce AWD performance.

If excessive tire wear is found, it is recommended that all four tires be replaced with tires of the same size, brand, construction and tread pattern. The tire pressure and wheel alignment should also be checked and corrected as necessary. It is recommended you visit a NISSAN certified ARIYA dealer for this service.

Wheel balance

Unbalanced wheels may affect vehicle handling and tire life. Even with regular use, wheels can get out of balance. Therefore, they should be balanced as required.

Wheel balance service should be performed with the wheels off the vehicle.

Spin balancing the wheels on the vehicle could lead to mechanical damage.

For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the Warranty Information Booklet.

Care of wheels

See "Cleaning exterior" for details about care of the wheels.

Emergency tire puncture repair kit

The emergency tire puncture repair kit is supplied to the vehicle instead of a spare tire. The kit must be used for temporarily fixing a minor tire puncture. After using the repair kit, it is recommended that you visit a NISSAN certified ARIYA dealer as soon as possible for tire inspection and repair/replacement.
